基于SPAD值精准施氮模式对烤烟产质量的影响
Effect of Precise Nitrogen Application Mode Based on SPAD Value on Yield and Quality of Tobacco
摘要
Abstract
[Objective]To investigate the effects of precise nitrogen application based on SPAD values on yield and quality of different tobacco varieties.[Method]Taking the tobacco varieties 105 and K326 as research objects,the nitrogen application methods were no nitrogen applica-tion(N0),105 kg/hm2(N1),two real-time nitrogen fertilizer management methods with SPAD values of 40(S40)and 43(S43)during the whole growth period respectively,to compare the effects of traditional application of nitrogen fertilizer and multiple application modes on flue-cured tobacco yield and quality.[Result]The agronomic traits and chemical quality of tobacco showed that S40 and S43 treatments were supe-rior to N0 and N1 treatments in both 105 and K326.For 105,the S43 treatment showed the best performance in terms of tobacco yield,output value,proportion of high-quality tobacco,and proportion of medium to high-quality tobacco,reaching 2 279.45 kg/hm2,67 152.60 yuan/hm2,36.66%,and 85.34%,respectively.The K326 variety showed the best performance with S40 treatment,reaching 2 438.21 kg/hm2,73 707.09 yuan/hm2,38.33%,and86.87%,respectively.[Conclusion]The precise nitrogen application mode based on SPAD values was ben-eficial for improving the agronomic traits,chemical quality,and output value of tobacco.关键词
